How to create a tv remote with fully working tv?

[ican]

Hello there

I need help to create a tv remote that will be connected to a virtual tv in labview so the remote will control the channel, volume even the brightness of the tv itself? And how to put video into labview?

Thanks

What exactly is a virtual TV? What is the source of the TV signal? You're going to need a minimum amount of hardware, like a TV tuner, unless you are planning to stream video from the Internet.

What i mean is i want to create a virtual tv that contains some video that will be putted in the labview. And there will be a remote tv that can change the channel (video), control the volume and brightness.

what he means is homework 🙂

it's not my assignment, it's my project to create a smart controlling remote that can control lights, curtains even tv but i don't know how to create the virtual tv

If you need to physically control external devices, you will need to start with something that can physically generate the IR just like the remotes you have right now. I know for a fact that an easily controllable (with an NI DAQ card) IR emitter is available at Radio Shack. An actual TV or use of a tuner card would need an IR sensor someplace. These are also readily available.

If you are going to simulate the hardware, then you are really going to be sending/receiving data from one application to another. There are many options for inter-process communication. TCP/IP, shared variables, etc. Search for discussions on the topic and you will find some examples.

Actually i'm using TCP/IP connection to connect between the tv and remote tv but the thing is i don't know how to create the logic for tv and the remote itself. Can you help me with some examples?

Thanks

I don't have any examples. I worked with real hardware. You might send a command followed by a value - for example 'ChannelChange,Up' or ChannelChange,15'. Parse out the command, wire that to a case statement and inside the case statement, take an action based on the value passed in.

This is not a special requirement and not really different from any other iteractive LabVIEW program. LabVIEW deals very similarly with any kind of data sources, be it a manual change of a control on the front panel, the result of a calculation, a message coming in over TCP/IP, an analog signal from a DAQ, etc. etc.

How familiar are you with LabVIEW in general? If you know LabVIEW, you should be able to easily do all this.

I'm new for LabView, around two months i have learned this but i'm not very understand about Labview. But the basic how do you put the video into labview?

Thanks
